kangpinghuang opened a new issue #2278: is not null query failed
URL: https://github.com/apache/incubator-doris/issues/2278
 
 
   query return invalid result with is not null predicate.
   
   to reproduce:
   
   CREATE TABLE `test` (
     `k1` tinyint(4) NOT NULL COMMENT "",
     `k2` smallint(6) NOT NULL COMMENT "",
     `k3` int(11) NOT NULL COMMENT "",
     `k4` bigint(20) NOT NULL COMMENT "",
     `k5` decimal(9, 3) NOT NULL COMMENT "",
     `k6` char(5) NOT NULL COMMENT "",
     `k10` date NOT NULL COMMENT "",
     `k11` datetime NOT NULL COMMENT "",
     `k7` varchar(20) NOT NULL COMMENT "",
     `k8` double MAX NOT NULL COMMENT "",
     `k9` float SUM NOT NULL COMMENT ""
   ) ENGINE=OLAP
   AGGREGATE KEY(`k1`, `k2`, `k3`, `k4`, `k5`, `k6`, `k10`, `k11`, `k7`)
   COMMENT "OLAP"
   PARTITION BY RANGE(`k1`)
   (PARTITION p1 VALUES [("-128"), ("-64")),
   PARTITION p2 VALUES [("-64"), ("0")),
   PARTITION p3 VALUES [("0"), ("64")),
   PARTITION p4 VALUES [("64"), (MAXVALUE)))
   DISTRIBUTED BY HASH(`k1`) BUCKETS 5
   PROPERTIES (
   "storage_type" = "COLUMN"
   );
   
   load some data with k1 = -1, the fire the following query:
   select count(*), min(k1), max(k1), sum(k1), avg(k1) from test             where k1 = -1 and k1 is not null
   
   doris returns invalid result.
   mysql> select count(*), min(k1), max(k1), sum(k1), avg(k1) from test where k1 = -1 and k1 is not null;
   +----------+-----------+-----------+-----------+-----------+
   | count(*) | min(`k1`) | max(`k1`) | sum(`k1`) | avg(`k1`) |
   +----------+-----------+-----------+-----------+-----------+
   |        0 |      NULL |      NULL |      NULL |      NULL |
